Abstract: 734,328. Valves. WINGFOOT CORPORATION. July 22, 1953 [Feb. 27, 1953], No. 20331/53. Class 135. [Also in Group XXXIV] In an inertia operated control valve for use in preventing skidding of wheels being braked of the type in which a valve for alternately connecting a brake pressure applying member to a source of fluid pressure and an exhaust passage is controlled by an inertia member normally rotated by the wheel but mounted for continued rotation upon sudden deceleration of the wheel, and characterized by having relatively rotatable valve members of which one valve member is the inertia member and spring return means is provided for normally holding the valve members in brake pressure applying position. The inertia operated control valve 1 includes a stationary valve shaft 2 which is provided with an end flange 3 having a plurality of ports 4, 5 and 6 suitably tapped for engaging with fluid conduits (not shown) used to connect the valve 1 in the brake system. The valve shaft 2 has a plurality of axially directed bores 7, 8 and 9 which connect with ports 4, 5 and 6 respectively. Normally the port 4 is the inlet port for hydraulic pressure-fluid for use in brake operation, the port 5 connects with a conduit leading to the brake operating means and the port 6 connects with the fluid-return line. Carried by the valve shaft 2 is a rotary valve member 13 which has formed integrally with it a flange 27 for connection to the housing 28 which rotates with the wheel of the vehicle to be braked. The rotary valve member 13 is provided with axially-spaced outlet bores 19, 20 and 21, 22. A rotor 23 is journalled on the outer periphery of the rotary valve member 13 and has a bore 24 extending therethrough with a pair of circumferentially and axially spaced recesses 25 and 26 being provided in the bore 24 as shown in Fig. 4. The recess 26 is provided for connecting the outlet bores 21 and 22 together as when a sudden braking force is applied to the wheel, the housing 28 and means connected thereto will be stopped abruptly. The rotor 23 will have appreciable inertia and will be moved circumferentially with relation to the rotary valve member 13, the recess 26 being moved to register with the outlet bores 21 and 22 to release the fluid pressure from the brakes. The'rotor 23 is positioned in operative relationship with the valve member 13 by a returnspring arrangement 32 which provides a resilient connection between the housing 28 and the rotor 23. The return spring arrangement 32 normally maintains the rotor in the desired operative position on the rotary valve member 13 so that the outlet bores 19 and 20 are normally connected and fluid supplied to the valve 1 under pressure will be passed to the brake actuation means through the valve means described in detail above. Specifications 662,029, [Group XXXIV], is referred to.

Abstract: 1334161 Recording apparatus ADDRESSOGRAPH MULTIGRAPH CORP 19 April 1971 [30 Jan 1970] 20607/71 Heading G1J [Also in Division G4] A meter 10, temporary recorder 14, and printer 12 are combined to print a measured value registered by indicia wheels 16 of the meter, print wheels 88 of the printer being set by elements 62 of the recorder, the positions of said elements serving to store the sensed positions of the indicia wheels 16. The recorder 14 comprises lugs 62 slidable on a board 40, spring-loaded detent racks (70), Figs. 4, 5, (not shown) holding them in any set position until reset. As the board 40 is pushed into the meter 10 along guide rails 36, lugs 34 of slidable rods 30 positioned in accordance with the meter reading act to set the lugs 62 of the recorder 14. Pushing the board 40 into the printer 12 along guide rails 82 causes the lugs 62 to engage lugs 86 on slidable rods 84 to set the print wheels 88 according to the set positions of the lugs 62. As the board 40 is withdrawn from the printer, a spring-loaded detent 98 returns the lugs 62 to their zero positions. Each rod 84 is connected to a respective print wheel 88 via a gear member 90 and a slidable rack 92, a torsion spring 96 acting on the gear member 90 to urge the rack 92 to the right (Fig.1). In the meter 10, radial pins 20 on the indicia wheels 16 act on fingers 26 of racks 24 which are connected by toothed sector gears 32 to the rods 30. The pin corresponding to each digit on an indicia wheel has a characteristic axial position on the wheel. The spring force on each detent rack (70) in the recorder is greater than the combined restoring forces of springs 28, 96 acting on the associated rods 30, 84 respectively. As described, the meter 10 measures petrol dispensed by a pump, the value on the register being the cost thereof. The board 40 of the recorder 14 has a slot 50 to register with the print wheels 88, a slot 42 to receive a credit card with raised type thereon, a slot 44 to receive a vendor's plate with raised type thereon, and a clip 46 to hold a form 48. The printer 12 may be separate from the meter 10, the recorder 14 being inserted first into the meter and then into the printer, or the printer may be mounted in a recess 38 of the meter, the sets of rods 30, 84 being relatively disposed as shown in Fig. 9. In this case the recorder registers with the meter 10 and printer 12 simultaneously, the print wheels being set according to the meter indicia wheels in a single operation.

Abstract: 635,730. Hydraulic drive; fluid-pressure servomotor-control systems. OILGEAR CO. Aug. 5, 1947, No. 21264. Convention date, Aug. 15, 1942. [Classes 69 (ii) and 138] [Also in Group XXVI] In a hydraulic drive for shafts or machine parts to be driven at constant speed ratio, shafts &c. 1, 2 are respectively driven by a motor 3 energized by a pump 4 and a motor 5 energized by a pump 6 having an hydraulicallyoperated block 15 for varying its displacement, a valve 25 being provided to control the flow to the motor 3, and means for causing a predetermined quantity of liquid to flow to or from the pump control to adjust the displacement of the pump 6 in response to the operation of the valve. The block 15 is urged towards a neutral position to stop the pump 6 by low-pressure liquid acting through a conduit 32 on a piston 16 and is urged away from this position by higher pressure-liquid acting on a piston 18. The pump 4 has a block 20 adjusted by a screw 21. A gear pump 31 is driven in unison with the pump 4 and draws liquid from a reservoir 29 and supplies it to the piston 16, any excess discharge being returned to the reservoir through a relief valve 33. Two meters 36, 37 are driven in synchronism with the motors 3 and 5. The inlet and outlet of the meter 36 are connected to the outlet and the inlet of the meter 37, respectively, by conduits 40, 41. The conduits 40 and 32 are connected by a pipe 43 and conduits 41 and 32 by a pipe 44 and a oneway valve 45 permitting flow into the pipe 44 which communicates with the piston 18 by a conduit 42. The relative displacement of the meters depends on the speed at which they are driven and determines the ratio between the speeds of the motors. To start and stop the motors synchronously, the block 15 is moved by a set volume of liquid displaced from a cylinder 51 which has a piston 52 whose stroke is adjustable through a conduit 54 and the pipe 42. The conduits 54 and 42 are connected by two oppositely-opening check valves 55, 56 arranged in parallel. Throttle valves 57, 58 are connected in series with the check valves 55, 56. With the valve 25 set as shown in Fig. I, the pump 4 is idling, but when it is moved into the position shown in Fig. 2 the pump 4 will actuate the motor 3 and supply liquid to the cylinder 51 to start the pump 6. If the discharge of the meter 36 exceeds the input of the meter 37, then the excess liquid in the conduit 41 will urge the block 15 to the right and increase the displacement of the pump 6 and hence the speed of the meter 37. Again, if the speed of the motor 5 exceeds that of the motor 3, the discharge from the meter 37 into the conduit 40 will exceed the volume drawn from that conduit and the excess liquid will pass into the reservoir 29. However, since the discharge into the conduit 41 is less than the volume drawn from this conduit, the deficiency is drawn from the conduit 42 and the block 15 is thus urged to the left.
